Electrical device including a circuit board having signal contacts and at least one ground contact along a surface of the circuit board. The electrical device also includes a communication cable having a differential pair of signal conductors, a shield layer that surrounds the signal conductors, and a cable jacket that surrounds the shield layer. Each of the signal conductors has a wire-terminating end that is engaged to a corresponding signal contact of the circuit board. The cable jacket has an access opening therethrough that exposes a portion of the shield layer. The electrical device also includes a ground-terminating component that is electrically coupled to the shield layer through the access opening and electrically coupled to the at least one ground contact.
